Residential EPDM Roof Replacement, October 2015, Edmonton

This client's home bears a low-slope roof that they wished for GRS to replace with an EPDM system. The crew of technicians went out to their location and completed the roof replacement in two days' work.   Materials List: October 13, 2015 Two technicians went out to the client's location and inspected the roof for what kind of deficiencies might be encountered during the roof replacement. During their inspection, they noted down the expected materials that would be required for the job.
  • 2x Rolls of EPDM
  • 7x Pails of EPDM bonding adhesive
  • 1x Pail of primer
  • 1x 6" roll of form flash
  • 2x Pipe boots
  • (84) 4' x 4' sheets of fiber board
  • 4x Roller cages and sleeves
  • 1x Box of seam tape
  Roof Report: October 16, 2015 The team arrived on site for 8:00am, and had their disposal bin arrive by 9:00. At that point, they were already underway ripping off the old roofing system and making good progress. It was after then that they found that there was no plywood with the order, just 2x6 boards. They departed to get the requisite plywood, and returned an hour later around noon. The boards were all mechanically fastened into place, with some of the EPDM laid atop it. The crew departed in the early evening, set to return the following day and focus on the remaining EPDM and metal flashing.

We removed the existing EPDM system until the plywood was exposed. Many of the boards were either rotting or had holes in them.

After installing new fiber boards over the assembly, we applied bonding adhesive to the underside of the EPDM.
    Roof Report: October 18 The reporting technicians notes were brief, but the site is now marked complete with the EPDM and flashing that was left over from the previous day's work. Everything went well and the roof was covered without any issue or hindrance of note.

Commercial EPDM Roof Replacement, October 2015, Saskatoon, SK

This client in Saskatoon contracted GRS to send out a crew that could replace their currently flat roof with a new EPDM system. The team went on location to rip out the old system and installed the requested EPDM without any issue.   Roof Report: October 7, 2015 This day, the crew arrived on site for 7:00am and began to rip off the existing roof system. The other team members didn't arrive until a short while later, right around the time that the crane showed up with the site materials. Between 12:30 and 12:45pm, the team loaded the roof and found that the order was missing insulation and seam plates. The site lead had to leave the site then, to pick up the missing supplies. By their return at 3:00pm the remaining team had torn off enough of the roof to expose some rotten plywood underneath. This too, had to be replaced, so another member of the crew was dispatched to pick up some replacement sheets. In the meanwhile, the on-site crew put down the ISO insulation boards and began gluing the rubber to it. It was around that time (~5:00pm) that the temperature began dropping below what the normal threshold for the glue's application permits, so the team weighted down the EPDM for the night and prepared the site for the rubber's adhesion the following day.

Bonding agent was applied to the underside of the EPDM and installed over the ISO boards.
    Roof Report: October 8, 2015 The crew assembled once more for 7:00am and got to ripping out the rest of the roof as the sun began to rise higher into the sky, warming up the site. When the roof itself was all torn out, they laid the EPDM's ISO insulation and then adhered the rubber atop it. This work carried on through the day, so that by the time they were prepared to leave the site, all of the rubber had been laid down and some of the plywood had been installed to the parapet walls where it had required replacing. The following day would only require some detail work to some curbs and seams. They expected that everything would be completed by 3pm and the site would then be entirely finished.

Completed flat roof EPDM installation.
      Roof Report: October 10, 2015 The crew finished the roof on this day, but not without a little bit of trouble during the process. One of the subcontractors hired on for the job was not able to carry out the metal work that they'd claimed, so a replacement had to be found on short notice. The replacement arrived on site and completed the metal work in a timely fashion that also measured up to the exacting standards on any GRS project. With the metal work done, the site was cleaned up and the crew departed, leaving this another completed site bearing the GRS stamp of approval.

To wrap up the site, we finished the metal work, including the perimeter flashing.
